AI research platform for reading, understanding and writing scientific papers
Open or upload a paper and ask questions, get plain-language explanations of highlighted passages, and pull out methods, results and limitations conversationally.
Search a large scholarly index spanning Google Scholar, PubMed and arXiv, then generate structured literature reviews and related-work sections from what you find.
An AI Writer for drafts, a paraphraser for academic tone, and a citation generator that formats references in popular styles.
Turn tables and results in a paper into structured data, and check whether a manuscript reads as AI-generated with a built-in detector.

The voice-activated teleprompter that keeps up with you
The script scrolls automatically as you talk and pauses when you stop, so pacing stays natural and you never lose your place.
Write new scripts or paste existing ones, then organize them with labels and find them when it is time to record.
Record takes right from the teleprompter and download them as MP4, keeping each video tied to its script.
Sync a tablet or phone to your computer so one device reads the script while the other controls the scroll.
